Merge pacs (picture archiving communication system) is designed and marketed for soft copy reading, communication and storage of studies produced by digital modalities, including digital mammography.On (b)(6) 2015 a customer reported that some patient priors included incorrect information after a data migration.The customer was receiving a print out from the ris system and found that mrn numbers were migrated over with the old numbers.This resulted in exams in incorrect folders.Merge pacs qualifies studies by mrn when processing a08 (patient update) and a34 (patient merge) requests from a his/ris.By default, if an a08 or a34 request is received that has an mrn that matches a patient but has the wrong patient name, the request will be rejected by the merge pacs.Merge pacs can be configured, however, to not check to see if the patient name stored in its database matches that sent by the his/ris and will instead return all studies that have an mrn that matches that sent by the his/ris (a process known as "global update").Merge was able to provide the necessary data so that the customer could do a comparison and identify duplicates to make sure the exams were in the correct folder.There was no report of patient injury.Reference: (b)(4).
